With the help of my student Roger Lee, I am preparing a package called
Matwrap. It is a Fortran 95 wrapper that links matrix operations and
decompositions to Lapack and the Blas. A preliminary version for real
matrices is near completion. But a final design decision has to be
made before it can be released, and I would like some input.

At the heart of Matwrap is a defined type for a matrix represented
within a rectangular array. The type has a component for the array
containing the matrix. Now by strict Fortran 95 conventions that
array must be a pointer array, which can be allocated and deallocated.
The difficulty with this is that the array must be explicitly
deallocated when it is no longer needed to avoid memory leaks, an
awkward way of doing things at best. There are also problems with
deallocating intermediate values generated by overloaded and new
operators.

Now there is an extension of Fortran 95 that allows allocatable arrays
in function results, dummy arguments, and defined types. (For more
see Chapter 13 of Metcalf and Reid's Fortran 90/95 Explained.) Since
such arrays are automatically deallocated when they are no longer
needed, this extension provides a solution to the problems of the last
paragraph. However, if the extension is not widely implemented, it is
not an option.

I would like feedback from Fortran 95 users about whether the
compilers they use support the extension and, just as important, if
the extension works. (The f95 compiler on my Sun workstation supports
the extension, but it does not work properly for returned function
values.) Please be specific about the compiler--source and version.
Thank you for your help.

Conference on Adaptive Methods for Partial Differential
Equations and Large-scale Computations
In Honor of the 60th Birthday of Joseph Flaherty
Rensselaer Polytechnic Institute Troy, New York
October 11 and 12, 2003

On the occasion of the 10th birthday of the Electronic Journal on
Numerical Analysis (ETNA), the conference

"ETNA: Following the flows of Numerical Analysis"

will be held in Kent, OH, May 29-31, 2003. The meeting, in the tradition of
past Kent numerical analysis conferences, will give participants an opportunity
to present their work and to interact in a friendly and relaxed atmosphere.

A web site for the conference, including a list of participants, is under
construction. It can be found at

http://lanczos.cwru.edu/~etna10

Please send e-mail to dxc57@po.cwru.edu or reichel@math.kent.edu if you
are interested in participating in the conference.

Daniela Calvetti and Lothar Reichel

on behalf of the organizing committee.

ETNA is available on the web at http://etna.mcs.kent.edu as well as on
CDROM.

Fast and robust parallel algorithms for the basic problems of numerical
mathematics are crucial for solving the problems in computational science and
engineering that arise today.

This workshop will be a forum for the presentation and discussion of new
developments in the field of parallel numerical algorithms, covering all
aspects from basic algorithms, software design and prototyping to efficient
implementation on modern parallel architectures and performance analysis.
Because of its importance for High Performance Scientific Computing
applications, the parallel direct or iterative solution of large systems
of linear and nonlinear equations will be of prime interest.

However, contributions dealing with problems other than numerical linear and
nonlinear algebra, or with general topics concerning parallel numerical
methods are also welcome.

Authors are requested to submit their papers by using our submission site
http://europar-itec.uni-klu.ac.at/submission.html (please indicate TOPIC 11).
The site will open not later than at the beginning of January 2003.
All accepted papers will be available at the conference in the proceedings
published by Springer-Verlag in the LNCS series.

MISSION STATEMENT EURO-PAR

Euro-Par is the annual series of international conferences dedicated to the
promotion and advancement of all aspects of parallel and distributed computing.

Gaithersburg, Maryland and Boulder, Colorado. Among the topic areas
for such research are applied mechanics, computational biology, materials
science, modeling of communications systems, image analysis, applied
optimization, Monte Carlo methods, data mining, mathematical software,
and quantum computing. For details see http://math.nist.gov/mcsd/postdoc.html.
The deadline for applications is February 1. The NRC program at NIST is
restricted to US citizens.

In addition to ongoing research, which will be partly interdisciplinary
between the areas mentioned, there will be an international visitors'
program in the form of special semesters on application fields.

The institute will be housed on the campus of the Johannes Kepler
Universitaet in Linz, a town of about 200.000 on the Danube, very close to
the Austrian Alps, and half-way between Vienna and Salzburg.

We are looking for PostDocs with a strong interest in one of the fields
above, who are also willing to work in an interdiscplinary environment;
doctorate in mathematics or a closely related field required. In addition,
we are also looking for Senior Postdocs, who could lead a group and would
also be expected to attract additional funding; they should have a
will be English. The positions are initially for up to three years, one
substantial publication record beyond the doctorate. The working language
renewal for three more years is possible depending on achievement.

Please send applications with personal and scientific data, copies of
relevant documents and a statement about scientific interests and
achievements to

and a copy to the area leader in whose group you want to work. There is no
deadline, the announcement remains open until all positions are filled; we
expect to be able to fill the first position on March 1, 2003.

A position as a postdoctoral researcher in the Division of Applied
Mathematics at Brown University will be open from summer/fall 2003.

The position is part of an ongoing effort to develop high-
